TRIGONOMETRY

            The word ‘Trigonometry’ is derived from the Greek words:

        ⇒                                                            Tri                         three

        ⇒
                                                            gon                        sides

         ⇒                                                            metry                    measure

                        “Trigonometry is the study of relationship between the sides and the angles of a triangle”


Trigonometric Ratios

Ratios of the sides of a right triangle with respect to its acute angles, called the trigonometric ratios of the angle.


Reciprocal Relations:

( i )sinA= 1 cosecA ( ii )cosA= 1 secA ( iii )tanA= 1 cotA from the above results, it follows that sinA.cosecA=1 cosA.secA=1 tanA.cotA=1

Quotient Relations: ( i )tanA= sinA cosA ( ii )cotA= cosA sinA
